To all who/mit 'mai/concerm Be it known that I, ROBERT J. BERRYMAN, acitizen of the United States, residing at napolis, in the county of AnneArundel and State of Maryland,'have invented cer? tain new and usefulImprovements in Methods or Processes for the Manufacture of ArtificialIce, of which the following is a specification.

My invention relates to an improved method or`process` for` thermanufacture of artificial ice, and the primary object ofthis inventionis to provlde means for forming ice in cans and removing it -fromthecans without theinecessity of removing the cans" from the tank. I

Another object is to provide an Improved method of manufacturing ice incans whereby it is possible to removeand dispose of' all impurities inthe water during the proc-y ess Vof freezing thereby obvia'ting thenecessity .of first .distilling and iiltering the water preparatory tothe manufacture of transparent .can ice.

With the foregoing objects and others 1n view, my invention consists 4infreezing the .water in cans so located in la tank that space is left .onall sides thereof, and- `after the.

completion of the freezing process introducing-a thawing medium in thespaceslaround the cans, whereby the .ice formed is thawed from the cansand it is renderedremovable Klo.

without moving the cans.

My invention further consists in the methodl of manufacturing ice whichconsists in freezing it in cans `from one or both sides toapredetermined depth, and .subsequently draining the .water leftremaining '1n the cans.

My invention further consistsin the meth-l od of manufacturing ice whichconsists in freezing it in cans from one or both sides to apredetermined depth, and subsequently draining thev water left remainingin the Cans, and a i-tating ewater i-n the cans during the reezingprocess. Myfnvention still further conslsts in cer tain procedure whichwill"y be I hereinafter out the claims.` n y v In theacoompanyingfdrawin 'sz-'Figure 1.-is a longitudinal, vertical sectionth .ough the machine. Fig. '2 is'a top planl vie ywith the coversremoved. Fig?) is-a; modification.

The tank A is preferably of steel, ali though it may be made of anysuitable ma- .terial and it is supported in a suitable framework B',between which andthe tank' there is a heavy insulation :1, of anysuitable material, Inside of the tank A there are lo ca ted'as many-cansC, C, as the capacity of the tank will admit, according to the size ofthe plant. These cans C, C, are preferably made of galvanized iron asviscustomary,

and they are -vmade in the desired dimensions. For example, the largeror inside across the bottom of the tank A, and they .are so arrangedwithin the tank that space is left entirely around each can. In thecoils of pipes.l 3, 3, are placed for conducting spaces interveningbetween everyV two cans,

the refrigerific mixture through the machine, this mixture vbeingintroduced through thevalve 4, and after it has passed through thecoils, it is returned through valve 5' in the return pipes 6. In lieu ofthe coils plate v 20 might be employed as shown in Fig. 3,

for the ammonia' gas or other -pcold ,liquid used in the freezingprocess. As the freezing mixture extends alongsidev the cans, the waterin the cans freezes from opposite sides,

toward ythe center, so that two cakes are i formed in all but theoutside cans, in which latter only one. is formed, as theffreezing.mixture only extends along one side of them. If the freezing processcontinuessuiiicientlylong, the two cakes of ice thus formed, will cometogether at the center, and form a single block of ice, and if desired,this may be 'done in every instance. For obvious reasons, which I willr'nenton,.however,'1 prefer that these cakes should not freezetogethenand my reason for this islthat it is my purpose in my method ofmanufacturing ice n ot to boil, anddstil the water used in themanufacture of the ice in order'to .remove the impurities, but on vthecontrary -to use raw or ordinary river or spring water,

and by agit'ating the water in the cans `while freezing it, VIconveniently accomplish this. l

by the introduction of compressed air or ozone through pipes 8,8,'11`her'ating it i through /fperforations vor openings the pipes sothat it rises through the water, and A by not freezing the cores of the'cakes or blocls of ice, that the ice formed is Aperfectly transparent,and free from foreign particles and all impurities, and that any to stopvthe freezing process when the cakes of ice freeze to a point withinabout two inchesor so of each other, whereupon the hollow plugs 9, 9,are removed' from the 'cans and the water remaining in the cans betweenthe cakes whichcatches and holds any impurities there may be insuspension,

I is then allowed to drain od.' Should'the the bottom of the cans.

plugs become frozen, they are easily removed by introducing warm wateror other medium into them previous to pulling them out. In theintermediate cans these plugs are located in the vcenter of the cans,whereas in the outer cans they are near the outer edge as indicated inFig. 2. These hollow plugs taper gradually from the point where theyenter the orifices in the bottoms of the cans upwardly, and thus whenthawed loose they have served as a mold to form an opening through theice, formed at the bottom of the can for the discharge of the impurewater at the core out through the orifice at In this way a perfectlyvclearand transparentblock of ic'e is formed, which is absolutely freefrom im A purities.

To facilitate the removal of the. cakes or blocks of ice from the cans,eye-bolts or hooks or other devices 10, 10, may be frozen therein asa`means for attaching the blocks to an overhead crane for removing themfrom the cans. Previous to removing the y ice from the cans, itssurfaces are thawed i out difficulty.

from the cans by introducing water or other liquid above freezingtemperature from the lpipes 11 through valve 12, which water or liquidsurrounds every can filling the spaces "left between them, and it ispermitted to :iear that the advantageous features of ooth can and plateice are preserved while at the same time s better product is ob tained,and it is handled with greater convenience and economy. Heretoforein canice, itll'has been 'the usuel practice to remove the cans and dip theminto a thawing vat in order to loosenand liberate the ice, but thislabor and expense are avoided by removing the ice from the can withoutdisl turbing the can, lin this invention, and furthermore by the processof this invention it is unnecessary to distil and filter the water usedin the manufacture of the ice.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts described without departing from thespirit and scope of my in vention, and hence I do not wish to limitmyself to the exact construction herein set fort-h, but Y Having fullydescribed my invention, what I claim as new and desire to secure byLetters Patent is z- 1. The herein-described process of manufacturingand harvesting ice, which consists in si'irrounding the receptacle inwhich the ice is formed by a freezing fluid'which fluid is reduced intemperature for freezing the contents of the receptacle, andsubsequently heated for thawing the ice from the receptacle.

2. The herein-described method. of manu facturing ice which consists insubmerging cans exposed on all surfaces and containing a measured orpredetermined quantity of water to be frozen into two plates of ice, ina iiuid medium, then conducting 'a rcfrigerating medium through saidfluid medium whereby to reduce its temperature and cause the freezing ofthe measured quantity of water, and subsequently substituting for saidfiuid, a thawing medium, whereby to heat the entire volume of thawingmedium uniformly whereby to thaw the ice loose on all surfaces of thecans in which it is formed.

3. The herein described methodv of man-ufacturing ice which consists infreezing water simultaneously from the several walls and bottom of thecans, molding an outletthrougli the ice formed on the bottom of the canin alinement with an orifice in the bottom. of said cam-and finallythawing the mold loose from .the ice, and drainingQthe water containedin the center of the ice out through the hole in the ice and the bottomof the can. l

el.. The herein-described method of manufacturing ice which.- consistsin surrounding a measured quantity of water inclosed in a suitablereceptacle with a freezing fluid whereby said receptacle is exposed onall surfaces to the influence of the fluid, then conducting` refrigerantthrough said Huid whereby to cause it to freeze the measured quantity ofwater, and finally conductinga thawing medium through the fluid wherebyto raise the temperature of the latter and cause it to thaw the 4iceloose.

5. The herein-described method of manullt) rfacturing artificial ice,which consists into quickly and simultaneously raise the temperature ofthe uid adjacent to -the outer surfaces of the ice -to cause-its releasefrom the receptacle in which the ice is formed.

ln testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.V
